on the main. frame 7 of the machine, rflepend ing'breoketsbeing proridedto receive the pivots of said hangers. The cross-shaft A} is swung to and from the driving friction disk by any suicehle means, for exmnple, such as that shown in my Patent 807,623 of December 19, 1905. The driven friction disk is moved along its slmft by means of a lever 3 to which isoonneoted the operating rod 3*", the ,i'orwsrcl. enrl of rod. being eonneoteil to any suitable form of opera-ting means (not show in hanger 6 mounted a. tubular box 9 which closed its outer and and is adapt-ed in icsin a. series of long rollers l0 which i oller bearing for one end of the shel he); is form-en with :1 reduced part its enter end which is adapted filo contain s l ill thrust bearing; and the 0nd of the K .e reduced to forni the shoulder 33 Wh adapted to engage said thrustbem'ing; s shim'n in Fig. 4. The tubular box 9 formed with. an exterior an nuler shoulder 14 which engages the inner side of the hanger 5 and holds seiClJtubula-r ho); alga-inst outward movementthro ugh said hanger. The hanger 6 formed with a tubular he 15 arlsptecl to re{ K's vl'" ers 1.6 which form n oi her end of ti shaft secured to the shaft 1 by means oi s rib 1.? is 21 beveled gem. hie-hing: with said beveled gear is a similar so 1 l rigidl 5e cured to the forward eml o? s longinniins-l shell :20, said shsl" 14f provii'leil with a. rib \\'l' l(fl1 is 5 in v l. i in s G')1I'S]')0l1ling groove in m said groove not being shown in ihe ornwiz tubular loo); 9 is provided at its ill-31.1 end Willi an annular redial firings 9 Lo which the lower half 22 of a gear casing is bolted. The upper part 22 of said casing is also ho coil to the flange 9"; end is bolted to the lower part h -mlts .2. Bolted to the rear side of this gear case is e rearward extending tubular snaitsupport23 "which surrounds the forward end of sin-zit 20, said shell support heing formed with a radial flange 23 h; which it eonneeterl to the gear case by means of bolts llhis shaftsuppor 's formed with s ohsnflher to re ceire long; rollers which form a roller hearing for said shaft. The gear 39 is formed with along hub 26 which is adapted to bear on said. roller 25, said hub being rigidly cured to the shaft against; longitudinal movement by means of the-screws 27 and the collar 28, as shown. clearly inhig. 4otghedrawingswith a reduced' c ambe 29 in which is arra Y thrust 'bearingeO; and the hub 26 of'ithe gear 5' -19 is formed with a shoulder 31 which is adapted'to engage said thrust'bearing. Said thrust bearing is held against rearward mo've mentby an annular wall 32, which forms the rear Wall of the chamber-29.- The collar 28 to cats against the rear side of this wall12 andb assists in holding the gear-iwheel against for-' ward movement on the shaft 20. Within the gear case is arranged a shaft protectingtuhe 3-3, the end of said tube closing the inner side of the gea r'casing22 and; forming a'dust proof cover' for the, shaft. It will be noted that the gears and the adjoining parts of the v shafts will be thoroughly protected, and that dust and moisture will 0 from.

The rear axle is formed in two parts or sections 34 and 34, the meeting ends of said sections being axially in line with the longitudinal ccnter'of the shaft The sections 45 34 and 34 of the said rear axle are each mountedwith-in a tubular casing 35 formed with the enlarged chambers 36 near its ends,

said chambers being adapted to receive long rollers 37 which form bearings for the m 30 closed section of the axle near each end of said axle section. Each axle section is formed near its inner end. with an annular shoulder or collar 38; and mounted on each axle section between said collar and the end 40, said gears facing each other, as shown in Fig. 5. On the hubs of these beveled gears, and bridging'the joint between the aide sections, is a sleeve 41 and said sleeve carries radial pins'42 which are arranged (llfiJHBtI'lCr ally opposite each other. These pins carry inions 4-3 which mesh with the axle gears 40.

he outer ends of the pins 42 are mounted in a yoke 44 which is formed with the bearings 45 45 rotatable on the hubs 39 of the beveled gears 40. The hub s 39 are held close to the.

collars 38 by means of flanged screw-caps 46 which embrace said collars and are threaded on the ends of said hubs.

The rear. end of the shaft 20 carries a beveled gear 47. This gear is formed with a long hub 48 Whichclosely fits the shaft 20 and is in sliding engagement therewith. The

shaft ZO'at, its rear end is provided with the longitudinal rib 49 which fits a corresponding groove in the rib of the gear 47, said rib being in sliding engagement with said groove. The object of mounting the shaft 20 in sliding engagement with the gear 47 is to permit said shaft to inovef'orward and rearward slightly when the driven friction disk 3 is moved to and from the driving friction disk This is a very important feature of in y invention. The inner ends of the casings-35 are each v 5 formed with an annular radial flange 50 to e .exclu ded thereeraeva which are bolted the upper entitle war ,sec-

tions 51 and 51 of a gear casing-. 'Whicli-Qin- 'closes the. gears connecting the with "the'sect on's of the.rear'a:g'l'e",{sa1d sections; f

the'gearcasingjbeing bolted together? 7 sup ort being formed with an inwardly ex-' ten ing flange 58 to hold said thrust bearing against forward movement; and the hub i8 being formed witha shoulder 59 to bring the forward thrust of the gear 47 on said thrust J bearing. A collar 60 is connected to the forward end of the hub' 48 and isadaptedtobear against the forward sidev of the liange 58 to hold the hub and they gear 47 'ina fixed. re-v lation with respect to the-shafhsupport 53 w and the gear casing 51 I v The gear 47 meshes with alarge beveled 4 gear 61 held by the *yoke 44 withinthe. gear casing. Between the-ends of the yoke 44 and the inner ends of the casings 35, suitable thrust bearings 62 are mounted, these bea ings also taking the thrust of the ear 4U. The gears 40 are rigidly connecte to the ends of their respective shafts by means of ribs 63 which fit corresponding grooves in the hubs of said gears.

35 of the section is the hub 39 of a beveled gear To each casing -35 is rigidly secured an upward extending spring support 64 adapted to receive the lower leaf of the elliptical springs, as indicated in dotted lines in Fig. 3, said springs being ada ted to support; the rear end of the vehicle liody.

The wheel hubs 65 are secured to the outer ends of the sect-ions of the rear axle in any suitable manner, the inner plate 66 thereof being formed with the inward extending annular flange 67 which fits around the adjoining end of the inclosing casing 35. Within the ends of these sections 35 are secured dust excluding washers of metal and felt as shown at 68 in Fig. 5. Secured to the inner plate of each of'the wheel hubs is a brake- 1 15} drum 69 within which is mounted the ex-- pending brake 70. The brake shoes are shafts extending into the adjoining brake drum and carrying an expander 75 which fits between the free ends of the shoes of the brake. Secured to each of said rock-shafts is an operating arm 76 to which a suitable rear end of the shaft support 23 eru'l sl d ng engagement tnerewitl'ij This is an g =1.

The forward end 01 this protecting tube thts closelywithin the is in hack and forth in thg, rear end of the shiii't su' jiport By this means the sliding joint between the gees. and the shaft 20'will he supported and protected in the shaft 'SU} })O1$ which is rigidly connected to the protecting tube, and the sliding joint between the protee-ting tube and. the shaft support will he at that point in the s sit \vhich is supported by and rigidly connected to the beveled gear 19. This arrengcinentis of iinport-sncein secur .ing strength, and also in excluding dust from the workin darts thereof.

The brake druin 85 is secured to the cross shaft and the brake shoes 86 are pivoted at 87, which is also the pivot oftne hanger .6. The expander 81 is pivoted in 21 depending part 82 of the hanger 6 F; and is the projet-ting arm for said expander.

From the ioregoing it will be seen that i provide an eiiicient shaft driving meohamis by which the eross shaft carrying the driven lrictiondisk 1'). he connected to the sections of the re 1e, and. the entire driving lnechanis n incl .sedwithin dust prooi ensings. t will also he noted that "l provide 1 new and desirable constructions? the rear axle, and difi'erentiel gearing, said dithered tisl gearing comprising the gears 40 the pinions and the main gear 61.
